Very, very happy with them! Unbelievable quality for the price - many said that in their reviews and yet I still didn't expect them to be this nice. All the way from the packaging to the extras and especially the glasses themselves. I've been stuck on wearing Serengeti's for 20 years and I'm not saying the lens quality is the same, but then they didn't cost a hundred bucks either. In fact with my Serengeti Drivers I can never tell that the lenses are photochromic, they always seem the same shade and can not be worn at night. The color change is quite dramatic making them wearable at all times. I wish they got a tad darker in bright sun/snow, but if the trade off is I can wear them in stores and when it gets darker out, I'll take it.
